"Warrant canary" is a colloquial term for a regularly published statement that an internet service provider (ISP) has not received legal process that it would be prohibited from saying it had received, such as a national security letter. The term "warrant canary" is a reference to the canaries used to provide warnings in coalmines, which would become sick from carbon monoxide poisoning before the miners would—warning of the otherwise-invisible danger. Just like canaries in a coalmine, the canaries on web pages “die” when they are exposed to something toxic—like a secret FISA court order.

Late last week, a group of four peers on Britain's House of Lords attempted to insert the entirety of the “Snoopers' Charter”—the Internet surveillance bill that was savaged by a Parliamentary overview, and abandoned by the UK's current coalition government—into a new counter-terrorism bill.

Under an incredibly tight deadline, thousands of UK citizens coordinated to warn the House of Lords what these amendments represented, and why they should oppose such an underhanded move. Over twenty-eight thousand messages were sent via EFF's action center to the 150 peers who are on Twitter: and that's not counting the emails, letters and phone calls.

You may have heard that the Patriot Act is set to expire soon. That’s not quite the case. The Patriot Act was a large bill, as were the reauthorizations that followed in 2005 and 2006. Not all of it sunsets. But three provisions do expire on June 1st: Section 215, the "Lone Wolf provision," and the "roving wiretap" provision.

The entity that’s conducting the most extreme and far-reaching surveillance against most of the world’s communications—the National Security Agency—is bound by United States law.

That’s good news for Americans. U.S. law and the Constitution protect American citizens and legal residents from warrantless surveillance. That means we have a very strong legal case to challenge mass surveillance conducted domestically or that sweeps in Americans’ communications.

Similarly, the United States Congress is elected by American voters. That means Congressional representatives are beholden to the American people for their jobs, so public pressure from constituents can help influence future laws that might check some of the NSA’s most egregious practices.
